President Lincoln—as he himself put it in conversation one day with a friend—“fairly ached” for his generals to “get down to business.” These slow generals he termed “snails.”

Grant, Sherman and Sheridan were his favorites, for they were aggressive. They did not wait for the enemy to attack. Too many of the others were “lingerers,” as Lincoln called them. They were magnificent in defense, and stubborn and brave, but their names figured too much on the “waiting list.”

The greatest fault Lincoln found with so many of the commanders on the Union side was their unwillingness to move until everything was exactly to their liking.

Lincoln could not understand why these leaders of Northern armies hesitated.
